Interactive package

Change the context. Compare the plans.

The local runtime evaluates candidate control sequences, predicts their trajectories and rejects plans outside the declared envelope.

Set the current telemetry, choose a goal and run the planner.

Results include actions, predicted state and constraint checks.

World contract

One Linux host with cgroup v2 workloads under bounded memory and swap pressure.

Temporal unit: 10_seconds. Supported horizons: 1, 4, 8.
